A writer for "Saturday Night Live" is facing an onslaught of criticism after tweeting a joke on Inauguration Day aimed at President Donald Trump's 10-year-old son.

The tweet in question came from "Weekend Update" writer Katie Rich who posited that Barron Trump, the only child between the president and first lady Melania Trump, will grow up to become America's "first homeschool shooter."

Rich removed the controversial tweet after three hours and then set her Twitter account to protected.

Many users pointed out the unwritten rule that children of politicians remain off limits when it comes to criticism--this is something President Obama's administration also dealt with throughout his eight years in office.
